A Ruby Library for dealing with different types of unit conversion.
Add this line to your application's Gemfile:
gem 'convert_unit'
And then execute:
$ bundle
Or install it yourself as:
$ gem install convert_unit
require 'convert_unit'
meter = ConvertUnit::Length.new(1, 'km')
meter.to('km') #=> ConvertUnit::Length.new(1000, 'm')
# Comparisons
ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(1000, 'm') #=> true
ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(1, 'm') #=> false
ConvertUnit::Length.new(1, 'km') === ConvertUnit::Length.new(1, 'km') #=> true
ConvertUnit::Length.new(1, 'km') === ConvertUnit::Length.new(1000, 'm') #=> false
# Arithmetic
ConvertUnit::Length.new(1, 'km') + ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(2, 'km')
ConvertUnit::Length.new(1, 'km') + ConvertUnit::Length.new(1000, 'm') == ConvertUnit::Length.new(2, 'km')
ConvertUnit::Length.new(1000, 'm') + ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(2000, 'm')
ConvertUnit::Length.new(1000, 'm') - ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(0, 'm')
# Valid units argument list
ConvertUnit::Length::UNITS_SYMBOL #=> { "millimeter"=>"mm", "centimeter"=>"cm", "meter"=>"m",
# "kilometer"=>"km", "inche"=>"in", "feet"=>"ft", "yard"=>"yd",
# "mile"=>"mi" }
#
# both short and full form are accepted in argument and case insensitive.
